Although laser TV is not what special fresh term, but for the laser TV understanding is not much in fact. There are too many online articles of the principle and overwhelming advantages of laser TV, but now give you to expose the five shortcomings of laser TV at present. A friend who wants to buy a laser TV can get to know it first.
The product can’t be moved and it’s difficult to install
Laser TV is a product of ultra short focus, that is to say, putting the laser TV on the TV cabinet can project nearly 100 inches of picture, so the laser TV does not need to be hoisted. But there is also a disadvantage on the use of the cabinet, that is, the machine is easy to move. Especially at home with children, many children are full of curiosity, so it is likely to move the laser TV product. Once the laser TV moves, it is difficult for the picture to be relocated.
The size of the screen and the matching of the edges and the curtain are all determined by the position of the laser TV. Therefore, once the position of the laser TV is moved, the user needs to re adjust the position of the screen edge and curtain. This process is not imagined so simple, especially for the projector is not too familiar with the user. Projection reflective ultra short focus, led to the laser TV screen does not reveal rectangular. Laser TV may be combined with trapezoidal correction functions in the adjustment of time, because of the adjustment process of laser TV is more complicated.
How to solve this problem? Users can use their own devices to fix the laser TV. Some vendors also provide pallets, pallets can be fixed with TV cabinets, and then laser TV and pallets are connected. This can solve the problem that laser TV is easy to move.
The phone can’t be directly projected on the TV screen
Many consumers are easy to ignore such a function when they buy Laser TV. This is the function of the wireless screen. The use of mobile phones is becoming more and more popular. Many users have made many video programs on mobile phones. If they can be projected onto TV synchronously, the effect will be very good.
Have a wireless projection function, for example, we buy a video platform specific member, you can directly use the mobile phone to watch the resources on the big screen, do not go to the laser TV platform to buy VIP membership, it not only save cost, but also enjoy a large screen, and has abundant resources. Now a lot of laser TV does not have this function, in fact, it is very unwise. So when buying laser TV, consumers must consider buying products that support the wireless screen. The later resources are rich enough.
How to protect children’s eyes
Some consumers have children at home, so they are worried about the safety of laser TV. Although the security of laser television has been tested, many national institutions have confirmed that normal viewing of laser television does not cause physical damage to the eyes of the user. But many children do not go the unusual way. They may directly put their eyes directly on the lens. The so-called “curiosity killed the cat”. What happens if there is such a situation?
It may not be a problem to watch the picture of the laser TV, but the eyes are directly aimed at the lens of the laser TV, and the energy of the laser is much bigger. Children’s eye structure is not yet fully developed, so if they have such a behavior, they may cause some harm to their eyes. Now a lot of laser TV does not deal with this problem.
However, some products began to take account of this problem, which provided a reliable solution. That is to install sensors on both sides of the lens. Only when obstacles appear in front of the lens of the laser TV, then the laser TV will automatically black screen. In this way, even a child’s inquisitive probe will not have the problem of injuring eyes with laser rays. The family has children, when buying laser TV, need to examine this function much more.
The interface is too subtle, plug is not convenient
Now the shape of the laser TV is almost the same. The lens is located on the top of the fuselage and the interface is located behind the fuselage. So when the normal use of laser TV, the interface of the laser TV will have to rush to the wall. This design problem is when plug all data lines, users often can not see the interface where mobile laser TV, there will be a re calibration problem we mentioned above.
Now people’s output devices are increasing, including players, cable boxes, game hosts, etc., including U disk. So many output devices cannot be connected to the laser TV all the time. Most of the time is the need to use when people will wire connected, so we need regular operation interface plug. A lot of Internet users respond to the interface of laser TV in the back, the operation is really very troublesome.
We think that frequently used interfaces, such as HDMI and USB interface, all need to be designed on the side of the fuselage, so that users can operate on interfaces. Some infrequently operated interfaces can be designed in the back, such as movie interface, audio input and output interface and so on. This kind of design is reasonable.
No auto focus function, very inconvenient
Another problem is the focusing problem of laser TV. Many laser TV products provide manual focusing mode. This way of focusing is not very convenient. Users need repeated operation to make sure. The current price of laser TV is not cheap. For a high-end product, it is necessary to provide auto focusing.
In addition, due to the principle of projector, after a long time, there will be some changes in the clarity of the picture, so laser TV needs to focus every once in a while. And at the time of installation, see the picture in the distance of the focusing is more convenient, the user can see the bigger picture for details of the performance is more understand. We think that auto focusing is still necessary for laser TV products.
